Application filedJuly 29, 1916.

To all whom it may concern:

Be it known that I, WILLIAM F. Dnsso, a citizen of the United States, residing at Somers, in the county of Tolland and State of Connecticut, have invented or discovered certain new and useful Improvements in Can-Straightening Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to can straightenin machines and has for its object to provide a convenient and efiicient machine for straightening or removing dents from milk cans and the like. To this end the invention comprises a straightening block having a pivoted connection with an operating lever so that the said straightening block may be carried far enough from said lever to adapt it to operate on cans of relatively large diameter, and still be adapted, by being brought into line with said lever, or approximately so, to be inserted into the relatively small mouths of such cans. The straightening block cooperates with a bed-plate preferably loosely supported on a table, and the can to be straightened will be placed on said bed-plate and the straightening block, which will operate from the inside of the can, will be pressed, by its operating lever, into forcible contact with the inside of the can located on said bed-plate. As the bedplate is loosely supported on the table referred to it may be moved into difierent positions, to accommodate different sizes of cans; or, if desired, interchangeable bedplates of different shapes and sizes may be provided for cooperation with the straightening block.

In the accompanying drawing Figure 1 is a side view of a can straightening machine embodying the present invention, and Figs.

2 and 3 are opposite end views thereof. Fig.

4 is a detail perspective view of the worksupporting bed-plate.

Referring to the drawings, 12 and 13 de note U-sha ed standards adapted to be secured to a oor or platform, and on the tops of which is mounted a support or table 14 preferably consisting of an angle-iron or steel bar having upwardly projecting side flanges The rear standard 13 affords bearings for a driving shaft 15 having a pulley 16 to be belted to any suitable source of power, and having a second pulley 16' connected by a belt 17 with a pulley 18 on a cam Specification of Letters Patent.

nected by a link 24 with the forward end of i the lever 22 is a pressing straightening block 25. The hinged or pivoted loose connection (which is preferred) of the block 25 with the said link 24, enables the said block to adjust itself more or less to the work, while the pivoted connection of the link-24 with the lever 22 permits the said link and block to be swung to a horizontal position, as denoted by dotted lines in Fig. l, in being entered intothe mouth of a can which may be too small to receive these parts when they are in a vertical or working position as shown in full lines in Fig. '1. Thus the straightening block 25 may be far enough from the lever 22 so that it may operate on a can of relatively large diameter, and ma still be readily entered into a relatively sma l lever 22 and still be adapted to be swung up so as'to be in line with said lever, or approximately so.

Loosely supported on the table 14 is a bed plate 26 which ,will preferably have a concave upper surface or seat to receive the cans to be straightened, said bed-plate having an opening 27 of suitable size and shape to receive a handle of a can, when necessary. The straightening block 25' is preferably formed with a transversely convex lower face so that it will roperly cooperate with the concave upper ace of the bed-plate 26, and between which bed-plate and said block the can body to be straightened will'b'e disposed in the straightening operation.

The belt 1? connecting the flanged pulleys 16 and 18 is normally slack, so that the shaft 19 will normally bestationary; but when a can to be straightened is placed in straightening position the attendant depresses the forward end of a treadle lever 28 thus forcing a belt-tightening pulley 29, at the rear end of said lever, against the belt 17 and thereby setting the shaft 19 in motion so as to cause the scroll cam 21 on said shaft to depress the forward end of the lever 22 to bring the straightening block 25 into forcible contact with the inside of a can supported on the bed plate 26. Said bed-plate 26 is free to be moved lengthwise on the table 14; to bring. different parts of a can lying thereon into register with the straightening block 25, and the can may be turned to different positions on said bed-plate for the same purpose; When the high part of the scroll ca-m passes the-lever 22', the weighted rear end of which rests on said ea1n,.the straightening: block 25- at theforward end of said leverwill be lifted by the overbalancing or' weighted rear end-0t aid lever. When the treadle lever 28 is released its forward: end will be lifted by a: spring 30 to slacken the belt 17 and thus'disconnect the shaft 19 from the driving shaiit 15, the upward move ment of said treadle lever, under the actio of saidspring, being: arrested by astop-pin 31 on the standard 12',

The operation ofthe machine will be readily understood from the foregoing, and

it will also be understood that the invention cooperating. with said bed-plate, a lever withwhich saidistraightening block has a hinged or pivoted connection so that it may be readily entered into' the relatively small mouth of a can by being swungupward intoline with saidlleveaanduneans for'operating said lever to force said straightening block toward said bed plate.
